t IMPROVEMENTIN BOTTLING SODA-WATER. UNDER. PRESSURE.

Specification forming part of Letters Patent No. 42,559, dated May 3, 1864.

To all whom a may concern.-

Beit known that I, HENRY CARsE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Machines used for Bottling Soda-Waters or Liquids Under Pressure 5 and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying1 drawings, forming part of this specification, and to the letters of reference marked thereon.

In all machines heretofore in use for this purpose the charging-cylinder is provided with an escape-valve so regulated as to allow the surplus gas to escape to prevent the strong outward pressure from bursting the bottle undergoing the operation of filling'. As the gas escapes it carries over With it a small portion of the acidnlated water, and also the sirup used in fiavoring, at caen stroke of the machine, this gas and water, as well as the sirup, being actually wasted, for previous to my invention no means had been devised for preventing this loss.

. The object of my invention is to save this sirup and water that was allowed vto pass off, and for this purpose I attach to the chargingcylinder (in place of the old escape-valve) a small iiuid-chamber, communicating with the interior of the charging-cylinder by means of a short pipe and faucet, the lever of this faucet being attached or connected to the crossbar carrying the cork-driver, and operating in such a manner as that when the cork is placed in the mouth of the charging-cylinder, and is partly driven down, the faucet Will open to allow the surplus gas and water, as well as the sirup, to enter the chamber. As soon as the cork is driven into the bottle the faucet closes, and remains closed until the next or succeeding bottle is placed in position to be filled and the cork inserted in the mouth of the charging-cylinder, when, as the cork is being driven down, the faucet opens, the pressure of the gas in the chamber forcing the uid into the bottle in advance of the cork, thus saving that which previous to my invention was allowed to pass oft' and go to waste.

To enable others skilled in the art to understand and make my improvement, I will proceed to describe its construction and operation by reference to the accompanying drawings, in which- Figure 1 represents a perspective view of my invention ready to be attached to a bottling-machine. Fig. 2 represents a vertical section ofthe same. Fig. 3 represents a longitudinal transverse section of the faucet and part-of the pipe. v

All the parts are lettered, and similar letters denote corresponding pieces in the several views.

I construct my invention by forming a small metal duid-ch amber, A, of any desirable shape, having an opening, N, Fig. 2, at the top, and a corresponding opening, G, Fig. 2, at the bottom, the opening at the top being closed by a valve, t, held down by a strong spiral spring, s, Fig. 2, kept in place by a tube, R, covered by a screw-cap, `B, having a hole through it for the guidance of the valvestem T, around which the spiral spring passes. The bottom of this chamber is attached to a short curved pipe, L, one end of which is screwed into the ch argin g-cylinder directly opposite th es upplypipe. Between the chamber A and the chargingcylinder of the machine is a faucet, U, operated by a long lever, D, and secured in place by a bolt, I), and screwlnutp, having a leather washer, x, placed between the working parts to prevent cutting and subsequent disarrangement.

The operation of my invention is as follows The screw y being inserted in an opening for that purpose made inthe charging-cylinder opposite the supply-pipe, as hereinbefore stated, the end of theV faucetlever D is connected by link or otherwise to the cross-bar of the cork-driver, which, as it approaches the completion of its upward motion, raises the faucetlever D to the position shown by the dotted lines in Fig. 1. This closes the faucet until the cork is forced partially down by the driver, when the faucet is opened and the surplus Water and sirup allowed to enter the chamber A through the openings m and F in the pipe L, where it is retained until the next or succeeding bottle is placed in position to be filled. By this time another cork is inserted in the upper end of the charging-cylinder and partially forced down toward the mouth of the bottle, n hen the faucet G is turned and the contents of thc chamber A is forced by the expansion of the gas into the bottle placed to receive it.

The valve t, at the top of the chamber A, is intended to regulate .the pressure of the gas as it enters therein to suit the pressure in the fountain; so that when the faucet C is opened the contents ofthe chamber will be forced by the expansiveness of the gas into the bottle in advance of that fluid that connes from the reservior. The proper degree of pressure necessary to accomplished this result is brought about by the operator turning the screw-cap B, which releases or presses down the spiral spring s on the valve t. As this invention is intended to be applied to the ordinary bottling-machines in use, a description of them is herein deemed unnecessary, as the principles of their construction and operatio are Well known.

@Ha-ving thus described by invention, Wha I claim is- 1. The application and use of a duid-cham ber attached to the charging-cylinder of a bot tlinglnachine for the purpose of saving th surplus sirup and Water passing off while ll ing one bottle, and forcing it into the succeed ing` bottle in advance of the Huid that come from the reservoir, substantially. in the man ner and for the purposes herein set forth.

2. The combination of the faucet C and es cape valve t with the Huid-chamberA .A an pipe L, when arranged and operating as her inbefore stated, for the purposes set forth.
